Behind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On one hand, we assume that we are indestructible. On the other hand, we think that any damage we impose on ourselves can be undone when wβfinally clean up our act.
If the evidence for how wrong the first idea is isn’t apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?
To a surprising degree, the answer is yes. Over the past five years, scientists have collected a wealth of data about what happens when aging people with bad habits decide to turn their lives around.
The heartening conclusion: the body has an amazing ability to heal itself, provided the damage is not too great.
The effects of some bad habits-smoking, in particular-can haunt you for decades. But the damage from other habits can be largely healed.
“Any time you improve your behavior and make lifestyle changes, they make a difference from that point on.”says Dr. Jeffey Koplan.“Maybe not right away. It’s like slamming on the brakes. You do need a certain distance.”
But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research: ---A study concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month. ---The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline ... Adopting healthy habits won’t cure all that bothers you, of course. But doctors believe that many chronic diseases-from high blood pressure to heart disease and even some cancers-can be warded off with a few sensible changes in lifestyle.
Not sure where to start? Surprisingly, it doesn’t matter, since one positive change usually leads to another. Make enough changes, and you'll discover you’ve adopted a new way of life.

When David Edwards founded the oPhone, he hoped scent (嗅觉的) messages would become the next big thing in the digitization of our online lives.
The device looked like a high-tech cruet set (调味瓶)， and allowed a friend with an iPhone app to send you scent messages alongside photos. Send a picture of your dinner, tag it with four different tones, and whoever is on the receiving end can sniff it from the vase-like tubes of the oPhone.
The oPhone didn’t take off, and the company has now shifted focus to a “scent speaker” called the Cyrano, which similarly uses a range of scent capsules to emit “play lists” of smells.
Compared to our real world interactions, our online lives are lacking in scent. Our digital culture, so soaked in visual and aural stimuli, is odorless (没有气味的). So why didn’t his marriage of smell and picture messaging excite more interest?
From a technical point of view, smell is simply harder to mass communicate than sounds and pictures. “There are two main technological obstacles to making smell transmissible by digital means,” explains biophysicist and author of Perfumes: The A -Z guide, Dr Luca Turin.
“First, there are no odor ‘primaries’like RGB or CMYK. Second, it has proved impossible to stimulate the olfactory epithelium (上皮组织) directly by any means tried so far. This means that it is currently impossible to induce a sensation of smell without there being an actual chemical in the inhaled air (吸入的空气).”
“The more we’re plugged into the virtual world, the more we deeply appreciate thecontrast-moments in our human, experience，” says designer and olfactory artist Mindy Yang.
“Intuitively, we realize that we are starved of certain sensations. With the rise of digital culture, society has become more interested in the missing sense-c-what we smell.”
This interest in scent isn’t only happening within the worlds of perfume and fashion. Over the past few years a number of cultural projects have set out to focus on the power of sensory experiences, from the use of a smell map, to the Tate Sensorium, which in 2015 let users experience visual art alongside smells, tastes and sounds.
Whether it’s devices like the oPhone that仕y to introduce scent into digital messaging, organizations are growingly aware of our culture’s desire for sensory experiences. In a time of virtual reality and scentless social networks, it’s perhaps no wonder that we as a culture have such a desire for something that instinctively feels real and authentic-even if it was made in a lab.
1.What can we learn about the oPhone?
A. The oPhone has defended our interest in what we smell.
B. The oPhone hasn’t caught on yet since it was founded.
C. The oPhone has swapped visual and aural stimuli for scent.
D. The oPhone is a vase tube to sniff specific messages from.
2.What makes it challenging to introduce scent into digital messaging?
A. The relevant tissue is impossible to stimulate directly.
B. Scent capsules should be applied to send out smells.
C. There exists no actual chemical in the inhaled air.
D. Sounds and pictures are easier to mass communicate.
3.What is the author’s purpose in writing the passage?
A. To promote the oPhone which can send scent messages.
B. To reveal the problems of the invention of the oPhone.
C. To predict the trend of the digitization of our online lives.
D. To introduce the oPhone based on smell-digital-technology.
Guide to Stockholm University Library
Our library offers different types of studying places and provides a good studying environment.
Zones
The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer.
